รายละเอียดสินค้า
Medium-temperature Sealants For Anodic Oxide Films Of Aluminum And Aluminum Alloys
Medium-temperature sealants for anodic oxide films of aluminum and aluminum alloys provide excellent sealing performance with a smooth, fine finish. These sealants effectively prevent common issues such as dye fading, powder film formation, and gray mist appearance.
Key Features
Superior sealing quality for demanding applications
Ideal for electronic product casings and high-end cosmetic packaging
Excellent cost-performance ratio compared to market alternatives
Light green powder formulation
Application Method
When preparing the bath solution, maintain pH at 5.5. Note that pH levels may fluctuate with use due to water, acid, and base introduction.
Use acid-resistant, high-temperature filters for solution filtration
Adjust pH with dilute acetic acid (to lower) or NaOH (to raise)
Product specific gravity varies by processing conditions (approximately 3-4m²/g)
Analytical Procedure
Combine 10ml sealing solution with 100ml pure water
Add 10ml 6N-ammonia water and 2-3 drops triethanolamine
Mix in 0.2g MX indicator (solution turns orange)
Titrate with 0.01M-EDTA standard solution until purple-red endpoint (A ml)
